Abstract

Danau Tamiyang memiliki inlet berasal dari aliran Sungai Riam Kanan dan memiliki outlet yang berada di bendungan karang intan. Informasi terkait tingkat pencemaran perairan di Danau Tamiyang masih sangat minim dengan adanya berbagai aktivitas masyarakat yang diperkirakan menyebabkan penurunan kualitas air. Penelitian berlandaskan pada parameter kualitas air secara fisika dan kimia menggunakan tujuh parameter seperti suhu, TSS, pH, DO, BOD, COD, dan nitrat. Tingkat pencemaran perairan Danau Tamiyang berdasarkan metode indeks pencemaran (IP) pada semua stasiun termasuk kategori cemar ringan dengan nilai indeks berkisar antara 3,03-4,37, yang diketahui bahwa parameter BOD adalah yang paling dominan menyebabkan pencemaran air. Hasil analisa menggunakan uji t pada taraf signifikan 0,05 terdapat parameter BOD yang menunjukkan nilai thitung>ttabel, yang artinya terdapat perbedaan antara stasiun 1 dan 2, sedangkan di taraf signifikan 0,01 perbandingan nilai semua parameter pada kedua stasiun tidak berbeda nyata.

Abstract

The aim of this research was to study the decline of organic functional group through the process of burning in peat. In addition, this study was also to examine the relationship between water content in peat and organic functional group after combustion (burning).  Peat drying was conducted in an oven at a temperature of 75°C with the interval of 0, 1, 2, 3, 4, 5 and 6 hours.  Each time interval had three replicates within two sets of experiments so that the total number of samples were 42 (experimental units).  Variables measured were moisture content, total acidity, COOH groups, and OH-phenolate.  The relationship between the water content with total acidity, COOH groups and OH-phenolate were determined by the equation y = bx + a.  The results showed that the relationship between the water content with organic functional group was linear.  While the relationship between peat water content with organic functional group after burning was irregular, although water levels through the process of burning have been greatly reduced. Keywords: Burning peat; organic functional groups; water content [How to Cite: Said R, FH Yusran, A Haris and S Asmawi. 2014.
